[SATDecorator] clicking zoom button flickers window content

[diver]

This is hrev38664.

Stack several Tracker windows (with lots of files) together. Clicking zoom button will flicker window content.

It got worse in recent revisions. Every click inside tracker produces several flickers. Most visible in VirtualBox, but visible on real hw too.

Fixed in hrev42487, thanks.

After cleaning up objects:

rm -rf generated/objects/haiku/x86/release/servers/app/
rm -rf generated/objects/haiku/x86/release/add-ons/decorators/SATDecorator/

and updating to hrev42490 I can still reproduce this one.

Ah I think I see what you mean and its probably an other issue than before. You mean the flickering in the title bar? I notice the problem before, e.g. when shifting the tabs in a stack. The problem is that the decorator draws tabs on top of other tabs. This is normally double buffered but the drawing of the buttons triggers a synchronous redraw...

[czeidler]

Hopefully finally fixed in hrev42493.

Still here in hrev42532.

Seems to be reproducible only with stacked tracker windows.

This is not a bug but normal and I also see it in terminal, probably every window. Try to stack two windows without S&T and you will see the same effect. The problem is that when you activate a window the complete window content is invalidated because it was not visible before and will be redrawn.

See Stippi's latest blog post if you are searching for a solution :-)

It's back again in hrev42615.

I still think that it is a bug in S&T because the flickering only occurs when two different apps are stacked together. For instance, if you stack Terminal+Tracker and try to resize or zoom (like in the attached video) this group you see that Tracker's window content flickers and redraws slowly. Whereas if you stack two Tracker windows and try do the same there is no flickering whatsoever.

Moving S&T related tickets out of R1 milestone (Prop #16).

Moving S&T related tickets back into R1 milestone as S&T is in fact now the default. My apologies.

Remove milestone for tickets with status = closed and resolution != fixed
